Mr Corbyn criticised the Tories' 'bellicose' approach to negotiations with the EU

The Brexit Secretary also said Britain will reject any attempt by the EU to keep European judges in charge of the rights of its citizens living in the UK after Brexit.

Mr Corbyn criticised the Tories' "bellicose" approach to negotiations and said he was "really struggling with what David Davis's strategy is - and Boris Johnson also, for that matter".

Asked at the Royal College of Nursing conference in Liverpool if he would agree to an exit fee before beginning trade talks, he said: "Clearly where there are legal obligations on long-term investment projects both in this country and other places, they must be adhered to, we must honour them.

"The others, clearly, will be open to a negotiation and we would negotiate on that. But we need to know where those figures come from, know what the details of it are.

"But I don't think we have to start this thing with a huge row or looking for areas of disagreement.”

He added: "The key issue has to be good relations between Britain and the EU in the future and that benefits both the EU and Britain actually, and hence the trade access which I see as the absolute priority."

David Davis said the 'row of the summer' will be over the sequence of talks with the EU

Asked again if he would agree to the EU's desire for a phased approach to talks, Mr Corbyn went on: "I would ask them to discuss all of the issues - day one, Labour government, we will discuss all of those issues, agree a programme for it.

"We will start off with what I've said about (the rights of) EU nationals and what our priority is.

"And obviously we are more than happy to discuss all the other issues with them, we will obviously adhere to our legal requirements - I think that's an important message to send to our colleagues in Europe."
